Hi
It's easier then you think. So, for example what I'm using in GxQuack
(envelope controlled wah pedal with some extra features) is:
Wah = (x : lowpass(1,6000.0) : highpass(1,10.0) :
reduce(max,256) : amp_follower_ud(attack,release) : min(1.0) :
max(0.0) );
instead a slider like this
Wah = vslider("Wah[name:Wah]", 0.5, 0, 1, 0.01) : Inverted(0) :
smooth(s);
Note, that this is with faust-0.9.73, so you need to convert that to
the new faust library structure.
attack is the "rise" time, release is the "fall" time.

For reference, here is the full GxQuack dsp file ( only work with
faust > 0.9.90) :
It's missing the definition of "amp_follower_ud" :( Herman, if you
understand the logic, can you please try to explain it with a
reproducible example? I' can't run your code to understand what you
meant by sending it to me :(
